In this manual, safety instructions for personal protection are 

marked with this symbol.
The relevant operational safety notes of the system and regulator 

are marked in bold.

Observe the following while installing the regulator and handling 

the battery:
Danger of explosion due to improper handling of batteries! Cor-

rosive hazard by leaking battery acid! 
Keep children away from batteries and acid! Smoking, fire and 

naked lights are prohibited when handling batteries. Prevent 

sparking and wear eye protection gear during installation. Observe 

and follow the handling instructions in the user manual and on the 

battery.
Solar modules generate power from light incidence. Even by low 

light incidence solar modules carry the full voltage. Therefore, work 

cautiously and avoid sparking during all work. Observe the cor-

responding safety precautions.             
During installation and electrical installation, the photovoltaic 

system’s DC circuit may carry twice its system voltage value (in the 

1 V system up to 4 V, 4 V system up to 48 V).
Use only well-isolated tools!
Do not use any technical measuring equipment that you know is 

damaged or defective!
When installing the power line ensure that no fire safety measures 

are damaged. The regulator may not be installed and operated in 

moist rooms (e.g. restrooms), or rooms, in which easily flammable 

gasoline mixtures may be present, such as by gas bottles, paint, 

lacquer, solvents etc. Do not store any of the mentioned mixtures in 

the room, in which the solar regulator is installed!
If the regulator is operated in a manner not specified by the 

manufacturer, the regulator’s constructive protective measures can 

deteriorate.
The factory signs and marking may not be modified, removed or 

made unrecognizable. All work must be performed in confor-

mity with the national electrical specifications and related local 

regulations! 
When installing the regulator in foreign countries, information 

concerning regulations and protective measures must be obtained 

from the relevant institutions / authorities.
Do not begin the installation until you are sure that you have 

technically understood the manual and perform the work only in 

the order provided in this manual!
The manual must be available during all work performed on the 

system, third parties included.
This manual is a component of the system regulator and must be 

included with the regulator when given to a third person.
